Correction factors
Amplitude correction factor (aI).
Range 0.9000 – 1.1000.
Representation 9000 – 11000, to get the correction factor aI,
the register (reg) is divided by factor 1000 (aI = reg / 1000).
Parameter name Register access
CORRECTION_FACTOR_L1 0x15D (RW)
CORRECTION_FACTOR_L2 0x15E (RW)
CORRECTION_FACTOR_L3 0x15F (RW)
CORRECTION_FACTOR_N 0x160 (RW)
